Abstract:
Optical devices and circuits are now key elements in a variety of applications, including biotechnology, automotive, food quality control, chemistry, etc. It is highly desired to find low-cost solutions to the photonics integrated circuits (PICs). In this paper, a comprehensive review of silica-titania (SiO
2
:TiO
2
) materials obtained by a sol-gel method come together with a dip-coating technique, and the numerical analysis of different optical devices based on the SiO
2
:TiO
2
optical platform are discussed. The sol-gel method is highly effective and does not require the use of expensive high-tech equipment. We discuss recent progress in our consortium on a cost-effective SiO
2
:TiO
2
optical platform for integrated photonics applications, with a concentration on materials, devices, and optical sensing principles investigated via numerical simulations.
